There's lots to learn here by reading as a guest. However, if you become a member (it's free, ad free and spam-free) you'll have access to our large vermiculite databases, our seed exchange spreadsheets, Mel's Mix calculator, and many more members' pictures in the Gallery. Enjoy.

I planted what I thought were golden wax beans (according to the package) but they don't appear to be very "golden." This is my first year gardening so I don't know much about the plant. Are these just regular beans?

I'm not really sure about the beans. I seem to remember my golden wax beans starting out golden and staying that way, but I could be mistaken. As for the squash, they look pretty small right now. You could certainly harvest them now, however they can grow pretty big (I've heard up to three feet long), but they're best when about 6 or so inches.
